Thread: 2005 V8 HSE Multiple Faults and getting to know the gap tool

With suspension and transfer case faults, I would have a hard look at the connectors at the LHS rear wheel arch. Continuity may check out ok, but if there is a wire with damaged insulation that can be sufficient to cause DTCs. I eventually found the fault on my machine by shaking each wire with someone sitting in the car to see if the display changed as I shook each wire.

Special thanks to Airmech953. I bought his spare transfer case module, installed and re-calibrated the transfer case. All the faults went away except I do have a new one around the Transfer case. Apparently there is a VIN mismatch, which I can only put down to the new transfer case module. Anybody got any ideas on that. I'll do some research and try and find the answer.


I drove her normally around the block a couple of times, special programs are available. So thats a good win.

I also tested the air suspension, i cant use the switch to lower it, so I'll look into that. But when raising, the rear raises quickly, but the front is very, very slow, in fact the compressor overheats half way up. So I'm thinking valve block rebuild at the front? Is there a middle valve block? Does someone sell the kits in Australia. Overseas shipping for something crucial is a bit slow right now.


Thanks again Airmech. I appreciate the part, it helped solve that major problem.

You'll need to program your vin to the TCM, can be done with a GAP tool if your vin is registered to it.
Pull the valve block out and clean it and match seals at a local oring seller.

You can also take the more expensive but simple approach and buy this kit

Was just hoping for a kit that was local and I could get quickly. I made some calls today abd it seems that everyone wants to sell new blocks, not kits. I'm not shocked by that result. Thanks for that though. Its kind of working at the minute, The compressor just gets too hot and the down switch isnt working, so I'll probably order a kit and wait.

The 4x4 airseals kit from the UK is perfect and will sort it out. It takes longer to remove and refit the solenoids blocks than to strip and fit the Orings to the blocks.

OK some great success today. Removed and cleaned the side air bag connectors. Put it all back togerther and all the airbag faults are gone. Its driving well, some transmission hesitation but that could be explained by it not having driven for a considerable amount of time. Ill get that looked at shortly, hopefully a good service will do the job.

Air con will need a re-gas, no cold coming out of that.

Otherwise its ready for roadworthy.

This weekend will be the rear tail gate not opening and the suspension switch no down. Then I'll put all the trims back together and send her off for the roadworthy. Hopefully driving it next week.

Thanks for all the help so far, not quite finished yet but its come a long way in 3 weeks.

I have more spare parts if you need
